Non-traumatic avulsion of the greater trochanter: a case report.

Apophyseal fracture affecting the greater trochanter is a rare injury in children. We report a case of non traumatic avulsion of the greater trochanter in a 13-year-old boy who presented with a history of pain about his right hip over the past few months. Hip radiographs, radioisotope bone scan and CT scan confirmed the diagnosis of avulsion of the greater trochanter with minimal displacement. The symptoms resolved after percutaneous in situ lag screw fixation. Radiographs 18 months after treatment showed fusion of the trochanteric physis.
